My 4invention relates to meansA lespecially adapted to be secured to the*w`alls,.roofs or` doors of railroad cars whereby lthe introduction of a Vsuitable vfumigating medium, into the car interior, while the car doors" and hatchcovers are closed, may bemade and therefore a thorough fumigation ofthe car Y interior and the commodities thereiny may beiv obtained. p Y Y My invention also has forV its Object the provision of means which lmay properly close and seal the introducing passage,

while at the same time preventing improper transference of temperatures to and from the car interior. y

The objects and advantages o fmy invenf tion will be readilycomprehended from the following detailed description of the accom` panying drawing, wherein-4- 20 A Figure 1 is a longitudinal sectional-view of my device applied to a wallofpara'ilroad car; only a portion of the wallbeing shown p as shown in Figure 1, The outer end of in section. a i y ,y

Figurel 3 is a top plan and transverse sec-j tional View of theouterend of the deviceasv Y 1 gassing machine, if such is employed, while applied in Figure 1.

Vand certain commodities carried therein,fre quire fumigation by a suitable gas used `for that purpose. ,Heretofore, this has been done before the car doors arelclosed,'by` an attendant carrying the apparatus or', ma-V chine containing the gas intoV the carby in! growth and parasites isY not obtained. n

My device is adapted to overcome these Y serious ob]ect1ons andto enablea transfer-v f ence or injection of `gas 1n such mannerthat end of the device; illustrating the closure` Railroad refrigerator or yother house cars,-

or open hatch plug orcover, and"h as it-'result'` a proper fumigation suiiicient tokill "fungus the fungus growth and parasites will be del f stroyed and proper fumigation of the commodities'within the car obtained. Y o

'v f l* u The plate 10 is provided with a' suitable' 65j' Y sizedfopening 13 preferably surrounded ori the outer-face ofthe plate with an annular enlargement or bossA portion as at 14;.while the rear sidefof'the yplate is provided with a tubular Aextension or conduity portion` 15 79":V

adapted to' extend into'asuitableopening or hole iin 'the year door, the wall ory the roof the opening in the member is shown slightly enlargedgor" flaredand threaded at 16,

in order that a suitable sealing plug may be, screwed therein 'for additional,se`ali1 ig,'` orto receive-a threaded connection from the' atthe-same time the unthreaded nozzle of themachine or Napparatus can' also be 'inl-vserted through the entire -vopening to ,the car'interior.`

lInits preferred form, theplatev portion 10 and the conduit portion 15 are pref-4 S5 VThese arms lare disposedforward'ly of 95 the main plate or casting 1()v with their inner ,faces preferably tapered and, increasing in thickness toward the bottom' as shown in Figure 1 to receive ,the lid or closure member 19, so that the member 19 will be 10Q The closurey me ber or lid 19 at one ,endY .is pivotally secured at 20 to casting'lO so Vas to permit the closuremember vto swing vertically upwardfinto the dotted line'gposition shown in Figure 2. Y

' Inorder to prevent too farv upwardjswinging movement of `the Vclosure memberI19,fI

prefer to provide the casting 4or plate with a stop lug 21. Y

t With the stop lug 21pos1tionedas shown,l itis apparent that the closure member '1 9 cannot be vmoved to fdead center4 and asi `a result"the lid willY drop into4 closed posi-V tiony through the action of gravity andf thus Y Y Y f ensure a closing ofthe opening intothe car I 20 Vif the operatorffshouldfail toV attendto same.

.In order topermit-easymanpulation of v the closure member orYlid 19, Iy provideit withv an extension or handle asx at 22 in YFi .ure 2. Y 25l ecured-in a wall ysheathing 17, and in aligmnent with the tubular portion or conduit 15 of the outer casting 10', .is a conduitV member-23 of predetermined length; andl one 'end of the- '30- conduit is preferably provided with a flange 2f1aperturedtoy receive 'suitablebolts' o-r screws asiat 25 forsecuring this :innen end Y v3.1 Yis'shownl provided" with asuitable handgras'pat 32 secured', to the plug inf any `suitable manner..

Y .With my improved device -it-is apparent thatl the car, aswell as the contained com- Y Y modities, may be easily andfproperly'fum'i- 7 gated after the carl yopenings have beenV Y 6o Yclosed 'and sealed by inserting thev nozzle or connection of the` gas containing cylinders or gassing machine inthe' outer orifice of the member10 after swinging the-lid 1.9jinto'Y theY dotted line open position; the orifice Y being alsoy shown threaded vat 16 to receive a threaded nozzle or connection when Vnecessary,' or toreceive a screw plug 'when detvenquantity of such medium; andthat such fumigation may be acconnlishedv while theV AA:car doors' vand-hatch covers are-closed and" sired for tightly sealing the car rafter it has sealed. With the non-conductingY or insu#V llating intermediateconnection cold will Ynot be transmitted from the car interior to the car 'exterior,' norwill heat be transferred from the car exterior to the car interior, and

hence ,the'refrigerating' condition of the car Y VwillnotV be interfered with.,

A device of the character described comprising a medium conveying conduit involving a temperature non-conducting portion; a cover member pivotally mounted adjacent to an orifice of the conduit so as to swing vertically; and means for limiting the vertical movements of the cover member and to cause the latter to close by gravity, a portion of said means and the cover member having Wedge action producing surfaces whereby the cover member is held against the orifice of the conduit.l f

5. In a medium introducing device `for railroad cars, a medium conveying sectional conduit arranged to extend from Vthe car exterior to the Vcar interior, the sections* being arranged in intereng'aging relation at their ends and one of the sections composed of temperature non-conducting material; and a closure member for one end of the conduit.
